ABSTRACT:
This invention relates to method and apparatus to intermittently apply a treating fluid to a wad of yarn in a texturing device comprising intermittently injecting the fluid under pressure into at least one port at the texturing device and impregnating the yarn with the fluid for a period long enough for the fluid to coat, react, or bond with the yarn. Continuous injection can be used for chemically reactive agents, which do not affect yarn coloration.
